Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a fishing reel, and more specifically, to a fishing reel that allows for highly accurate measurement of fishing line reeling and reeling during fishing. It's about reels.

(b) Prior art and problems Recently, fishing reels have been equipped with a mechanism that measures the length of the fishing line let out from the spool or the length of the line wound onto the spool and displays these digitally. have been doing so, and
These functions are now controlled by microcomputers.

However, as a method of measuring the amount of fishing line let out and the amount of winding, as shown in Japanese Patent Application Laid-Open No. 57-155931, etc., the rotation of the spool is detected by a sensor, and the sensor detects the rotation of the spool. This is carried out by counting the pulse signals that occur, importing this counted value into a microcomputer every calculation cycle, calculating it, and outputting the calculation result to a display section.

However, the winding diameter of the fishing line on the spool decreases when the line is paid out and increases when the line is wound up, so the amount of line paid out or wound up per revolution of the spool changes depending on the winding diameter of the line. do. Therefore, simply counting the number of pulses per unit length (for example, per 1 m) obtained from the rotation of the spool does not allow highly accurate yarn length measurement.
If the wire diameter of the thread used changes, the rate of change in the winding diameter of the thread during unwinding and winding will also differ, so the measurement method described above allows for highly accurate thread measurement according to the thread diameter. There was a problem that the amount of unwinding and winding could not be measured.

(c) Purpose of the Invention The present invention solves the conventional problems as described above, and its purpose is to improve the measurement accuracy of the length of the unreeled yarn and the length of the wound yarn after unreeling, and to To provide a fishing reel which prevents accumulation of errors between the two even when winding is repeated.

(d) Structure of the Invention For this purpose, the fishing reel of the present invention includes a reel body, a spool rotatably supported by the reel body and around which a fishing line is wound, and a sensor for detecting rotation of the spool. The signal from this sensor is counted up to count the number of rotations of the spool when the thread is let out, and the up/down counter is counted down based on the signal from the sensor, and the thread is let out based on the count value of this up/down counter. A means for calculating the line length and winding line length, a display section for displaying the calculated line length, and a means for calculating the line length and a display section for displaying the calculated line length; A thread diameter input means for selecting various thread length calculation formulas created to approximate curves obtained through actual measurements in accordance with the diameter of the fishing line wound on the spool, and a feed-out amount and wind-up amount. and means for forcibly resetting the display on the display section to zero at the end of winding when a predetermined error setting value is reached.

FIG. 4 shows the procedure of the mode switching means by operating the mode switching switch 18, and FIG. 5 shows the procedure of the thread diameter input means.
The figures each show the procedure of the total yarn length input means, and FIG.
is stored in

Next, the operation of the embodiment of the present invention configured as described above will be explained.

First, when the power switch 7 is turned on, the microcomputer 10 is initialized. When the mode changeover switch 18 is intermittently and sequentially pressed in this state, the microcomputer 10 selects the yarn diameter input mode shown at step S1 in FIG. 4, the total yarn length input mode shown at step S2, and the total yarn length input mode shown at step S3. The mode is sequentially switched to yarn length measurement mode.

Steps S1 to S3 shown in FIG. 4 are performed cyclically by operating the switch 18, and this is called the normal mode. In this normal mode, when the on/off mode switch 21 is pressed once, the mode becomes an off mode, that is, a state in which all inputs are not accepted. When the on/off mode switch 21 is pressed again, the mode returns to one of the normal modes before the off mode.

When the microcomputer 10 is set to the thread diameter input mode, the "LINE" 5a of the display section 5 lights up or flashes, indicating that the mode is the thread diameter input mode. At the same time, the thread diameter is enabled to be specified, and the thread diameter input processing routine shown in FIG. 5 can be executed by repeatedly turning on the set switch 19.

In the thread diameter input processing routine shown in FIG. 5, when the set switch 19 is repeatedly turned on, steps S10 to S1
2. Steps S13 to S15 and Step S16
- S18 are executed cyclically, and, for example, three types of thread diameters, 0.28 mm, 0.30 mm, and 0.35 mm, are displayed and the corresponding thread length calculation formulas are set.

First, when the set switch 19 is turned on for the first time, the display section 5a and the selected thread length calculation formula are reset in step S10, and then the thread diameter shown in step S11 is reset.
0.28mm display processing is executed. That is, thread diameter 0.28
mm data is read from the ROM 12, and the data is sent to the display unit 5 through the output port 15.
is output, and the numerical value ".28" is displayed on the thread diameter display section 5b.
Display. Then, the process moves to the next step S12, and a calculation formula y = a ₁ x ³ + b ₁ x ² + c ₁ x (however,
y: yarn length, x: spool rotation speed), and at the same time, constants a ₁ , b ₁ , and c ₁ of the primary to tertiary terms are set. These constants a ₁ , b ₁ , and c ₁ are suitable for yarn length measurement with a yarn diameter of 0.28 mm, and these constants and the cubic equation are
It is stored in ROM12. Then, if you complete the ON operation of the set switch 19 once,
A thread diameter of 0.28 mm and its thread length calculation formula will be selected.

Further, if the set switch 19 is pressed once more, the process advances to step S13, and the display of ".28" on the display section 5b that was set when the set switch 19 was operated for the first time is reset.
The corresponding yarn length calculation formula is also reset. Then, the process advances to the next step S14, and a process for displaying the thread diameter of 0.30 mm is executed. In other words, by reading the data for the thread diameter of 0.30 mm from the ROM 12 and outputting it to the display section 5 through the output port 15,
The numerical value ".30" is displayed on the thread diameter display section 5b. Next, proceed to step S15 and set the thread diameter to 0.30.
Set the calculation formula y = a ₂ + x ³ + b ₂ x ² + c ₂ x that is suitable for measuring the yarn length for unwinding and winding in mm, and at the same time set the constants a ₂ , b ₂ , c ₂ for the 1st to 3rd order terms. Set.

Furthermore, when the set switch 19 is pressed, the process proceeds to step S16, where the display and calculation formula set for the second time are reset in the same manner as described above, and the process proceeds to the next step S17, where the thread diameter of 0.35 mm is displayed. When this yarn diameter display process is completed, the process proceeds to step S18, where a calculation formula y=a ₃ +x ³ + that is suitable for measuring the yarn length for unwinding and winding with a yarn diameter of 0.35 mm is calculated.
Set b ₃ x ² + c ₃ x, and at the same time set constants a ₃ , b ₃ , and c ₃ of the first to third order terms.

Therefore, when the line diameter of the fishing line 3 wound around the spool 2 is displayed on the display section 5b, if you stop turning on the set switch 19, the formula for calculating the line diameter displayed on the display section 5b will be set. Based on this calculation formula, the length of the unwinding yarn and the length of the winding yarn are calculated.

Next, the processing procedure for inputting the actual total length of the thread wound around the spool 2 will be described with reference to FIG.

When the microcomputer 10 is set to the total yarn length input mode by operating the mode changeover switch 18, "CAP." 5d on the display section 5 is lit to indicate that the mode is the total yarn length input mode, and at the same time, A process of setting data corresponding to the maximum display value of the yarn length display section 5c of the display section 5 in the RAM 13 as shown in step S20 in FIG. 6 is executed. That is, the yarn length display section 5 in this embodiment
The maximum display value of c is "199" (unit: meters), and the corresponding data previously written in the ROM 12 is written to the RAM 13 by the CPU 11, and the maximum numerical data is output to the output port 15. is output to the yarn length display section 5c, and "199" is displayed on the yarn length display section 5c. next,
Proceeding to step S21, it is determined whether the set switch 19 has been pressed. This judgment result is “YES”,
That is, when the set switch 19 is pressed once, the process moves to step S22, and the switch signal is taken into the CPU 11 through the input port 14, and is input to the CPU 11 through the input port 14.
Perform subtraction by 1. As a result, the numerical contents stored in the RAM 13 are counted down by -1, and at the same time, 199-1=198 is displayed on the yarn length display section 5c (step S23).

Thereafter, if the set switch 19 is turned on intermittently in the same way, the contents in the RAM 13 will be counted down one by one, and the displayed contents on the yarn length display section 5c will also change from 198→197→...→0. .
Therefore, when the value displayed on the yarn length display section 5c reaches a value corresponding to the substantial total length of yarn wound on the spool 2, for example, "130" m, if the on/off operation of the set switch 19 is stopped, 130m is set in the RAM 13 as the actual total yarn length data. Then, when the reset switch 20 is turned on, the yarn length value being displayed becomes zero.

Note that if the set switch 19 is pressed continuously for about 1 to 2 seconds, a predetermined number of free-running pulses, for example, 8 Hz, will be generated. In combination with this, the total yarn length can be set more quickly.

Next, the operation of measuring the length of the fishing line 3 let out and the length of the wound line during cast fishing will be explained according to the processing procedure shown in FIG. 7.

When actually fishing, follow step S in Figure 4.
1. After passing through S2, the mode changeover switch 18
Set the microcomputer 10 to yarn length measurement mode by operating . As a result, "DIST." 5e on the display section 5 is lit, indicating that the yarn length measurement mode is in effect.

In this state, when a fishing rod (not shown) with the reel body 1 attached is swung down, a tackle (not shown) connected to the fishing line at the tip of the rod is thrown toward a point, and as the tackle flies to the point, The fishing line 3 wound around the spool 2 is sequentially let out, and at the same time, the spool 2 is rotated in the line payout direction. This direction of rotation is defined as forward rotation.

When the measurement processing program is thereby started, first, in step S30, it is determined whether or not the yarn is being let out. This is because the magnetic field of the magnet 16b fixed to the spool 2 causes the pair of Hall elements 16 to
It is determined by which part of a is crossed first, and if it is determined that the thread is being fed out, the process proceeds to the next step S31, where the up/down counter 17 is set to perform an up-counting operation.
The voltage signal generated from the sensor 16 every rotation of the spool 2 is converted into a pulse signal by the waveform shaping circuit 16c, and this is converted into a pulse signal by the up/down counter 17.
Count up by adding to . Then, proceeding to the next step S32, the count contents of the up/down counter 17 are taken in, and based on the taken count value, the payout yarn length D is calculated by y = a ₁ x ³ + b ₁ x ² + c ₁ x. Execute. In this case, the diameter of the fishing line used is 0.28 mm.

The thread length D calculated in step S32 is
1 built-in lens (not shown) (step S33). The latched yarn length D is outputted to the yarn length display section 5c in the next step S34, and the calculated yarn length D is thereby digitally displayed on the yarn length display section 5c. Step S
When the process of step 34 is completed, the process returns to step S30 again, and the process after step S31 is executed, and the display contents of the yarn length display section 5c are changed in the upward direction in accordance with the length of the yarn being let out each time. At this time,
The numerical value displayed on the yarn length display section 5c changes in units of 1 m. When the device lands on the water and the thread payout stops, the thread length display section 5c displays the thread length at the time when the thread payout stops.If this display value is, for example, "50", This indicates that the fishing line has been let out for 50 meters, and at the same time indicates that the bait casting point is approximately 50 meters from the shore.

On the other hand, when the tackle sinks (counts down) to a predetermined water depth after landing on the water, the rod and reel are operated to move the tackle towards the shore. That is, when the handle 9 is rotated to rotate the spool 2 in the winding direction (reverse rotation), the fishing line 3 is moved from the spool 2.
The microcomputer 10 executes a winding processing routine at the same time as the film is sequentially wound.

That is, when the spool 2 is rotated in the winding direction, the rotation and direction are detected by the sensor 16, and by inputting the signal to the microcomputer 10, it is determined that the spool 2 is not being fed out in step S30 of FIG. , proceed to step S35,
The up/down counter 17 is set to function as a down counter. Then, by inputting a pulse signal for each revolution of the spool 2 to the up/down counter 17, the count value counted when the thread is let out is counted down by -1. In the next step S36, the count content of the up/down counter 17 is taken in, and based on this count content, the calculation of y=a ₁ x ³ +b ₁ x ² +c ₁ x is executed to determine the winding yarn length d. Calculate. In step S37, the winding yarn length d is changed from the unwinding yarn length D.
This subtraction result is latched in the register built into the CPU 11 in the next step S38, and the process proceeds to the next step S39, where the latched yarn length D-d is output to the yarn length display section 5c. As a result, the calculated yarn length D
-d is digitally displayed on the yarn length display section 5c.

When the process of step S39 is completed, the process proceeds to step S40, and it is determined whether the subtracted value of D−d in step S38 is D−d=2m.
That is, it is determined whether the length of the thread from the tip of the rod to the hook has reached approximately 2 m, and if "NO", the process returns to step S36 and the calculation of the winding thread length d is executed. The determination result in step S40 is D-
When it is determined that d=2, step S4
1, an alarm drive command is sent out, and the alarm 23 is repeatedly sounded in a "pitsu, pitsu" manner to warn the angler that the fishing line 3 that has been let out is reaching its end. At the same time, this prevents the tackle from colliding with the rod tip and breaking the rod tip due to excessive winding of the fishing line 3. That is, the rod tip is protected. When the thread that has been let out is completely wound up, the process proceeds to step S42, where a reset process is executed for the thread length display section 5c. This allows the winding force on the spool 2 to change due to a change in the attractive force of the line, such as when a fish hits it, and the winding diameter of the line to change, causing an error between the line payout amount and the winding display value. This is eliminated, and the yarn length can always be measured from the zero display state when the yarn is let out. Note that when the latched yarn length is D-d<1, D-d is forcibly set to 0, and step S42
Proceed to.

That is, even if the fishing line 3 is completely wound up, even if the calculation result of (+) or (-) is output to the line length display section 5c due to an error in the amount of reeling out,
By resetting this, the above-mentioned display error can be eliminated for each fishing operation.
This means that the cumulative error can be eliminated and the length of the unreeled yarn can always be displayed with high accuracy.

In Figure 8, the horizontal axis shows the amount of yarn that is actually wound on the spool (or the amount of yarn that is wound up).
The vertical axis is the spool rotation speed at that time, and it is a characteristic diagram showing the relationship between the thread payout amount and the spool rotation speed as an actual value.The curve is for a thread diameter of 0.28 mm, and the curve is for a thread diameter of 0.30 mm. The curves show those with a thread diameter of 0.35 mm, and in order to approximate these actually measured curves, constants were set for each thread diameter using the approximate formula for calculating the thread length of y = ax ³ + bx ² + cx (a ₁ ~ a ₃ , b ₁
~b ₃ , c ₁ ~c ₃ ) so that the yarn length can be calculated with high accuracy. Here, the constant changes depending on the type of yarn, the diameter (thickness) of the yarn, the elongation rate of the yarn, etc., and is determined by the specifications of the reel. Then, repeated data on unwinding and winding is collected for each thread diameter, and the average value is calculated by taking into account variations in thread tension, thread thickness, etc.

Although the thread length calculation formula based on the spool rotation speed in the above embodiment is determined by a cubic formula, it may be determined by a quadratic formula. In this case, the calculation load on the microcomputer can be reduced. In addition, the input data for the thread diameter is 3
Not limited to types.

(F) Effects of the Invention As explained above, according to the present invention, a calculation formula suitable for the fishing line diameter is selected for each fishing line diameter, and the line length can be measured and calculated based on this calculation formula. , the accuracy of measuring the length of the line being let out and taken up can be improved, and at the end of the winding of the fishing line that has been let out, the displayed value is automatically reset to zero while subtracting the amount of reeling from the amount of reeling out. Therefore, even if unwinding and winding are repeated, there will be no display error between the two, and the yarn length, especially the unwinding yarn length, can be accurately displayed.
